PURPOSE:To provide a ring-shaped battery which forms the main body of a ring or a bracelet by forming a battery in a ring shape. CONSTITUTION:A mercury battery 1 is manufactured in such a way that a zinc negative electrode 3 comprising pressed amalgamated zinc powder is arranged in the center, and an absorbent material layer 4 impregnated with potassium hydroxide is placed so as to surround the zinc electrode 3, and a mercuric oxide positive electrode 5 is arranged so as to surround the absorbent material layer 4, and they are accommodated into the ring-shaped stainless steel case 6. A flat part 6a forming a positive terminal and a projected terminal 7 forming a negative terminal are faced with a space in a gap 2. An LED segment 8 is fitted so as to be able to mount or demount freely. Therefore, by replacing an LED, emitting color can be changed. |
